Application filed February 213, 19 23) Serial No. 620,748.

This invention relates to a rolling machine.

. particularly adapted for rolling an inwardly bead about the periphery of at extending the bead so rolled member so as to cause to extend into'a corresponding recess formed about the periphery of the member to which it is to be attached.

The main object of the invention is to provide a rolling device so arranged and combined with a holding or clamping vise as to manually roll an inwardly extending head in the peripheral wall of a female piece of work into acorresponding recess or groove formed on the peripheral surface oi? a corresponding male piece of work disposed in tree Working relation within said female work, such rolling being carried out by the manual rotation of said female work against a roller means having relatively fixed pivot means, whereby the completion of such rolling process is automatically indicated by the frictional resistance of'said bead in said recess, due to the corresponding resistance to the manually rolling] thereof, by which arrangement it is very easy to form said head in loose working relation with said recess and thereby effect what is known as a. running fit therewith.

One feature of the invention resides in the holder or vise for holding such male piecesof work in place while being operated upon, and another feature of the invention resides in the means associated with the vise or holder for operating upon the work and so rolling it as to manually control the rolling operation.

he full nature of the invention will be understood from the accompanying draw ings and the following description and claims.

In the drawings, Figure 1 is a plan view looking; down upon the vise and heading rollers with the work removed therefrom. Fig. 2 is a side elevation showing the work mounted in position, having the operating wrench mounted in place. Fig. 8 is a central vertical section through the work showing the operating Wrench secured therein and one oi the beading rollers in operative engagement. Fig. 4; is a view taken on the line of Fig. 1 showing a front cle ration of the beading rollers.

. in the drawings there is shown a vise or work holder adapted to be rigidly secured to a bench or the like having a base 10 and there is a top plate a centrally recessed supporting standard 11. V

Extending outwardly from the standard 11 and braced by the web 12 so as to be rigid with respect thereto, there is a tool containing slide 13 provided with an internally screw threaded projection 14. Across the top of the sides of the slide 13,

15' rigidly secured thereover by the screws 16. Slidably mounted within" the slide, there is a tool 17 which may be torcle'd'forwardly by the screw 18' and operated by the handle 19. Rotatably inountedin the forward edge of the tool 17, there is a pair of rollers 20 provided with beadtorm'ing flanges 21. Extending diametrically throngh the side of the supporting standard 11, there is a securing screw 22 operated. by the handle 23.

The work may consist of the hollow shaft having a head25 thereon upon which it is desired to secure the connecting key 26. The head 25 is provided with a screw threaded radial opening through which the thumb screw 27 may extend. Extending about the periphery of a reduced portion of thehead 25, there is formed an annular recess 28- into which the metal forming a portion of the surrounding-shell of the key 26 is adapted to be forced by the heading operation. For turning the work in the holder, here is provided a wrench having a head 280, and radial projections 29 adapted to fit in a slot in said key as shown in extending downwardly through the bottom of the head 280- through the center of the key 26 and into the head" 25 and shaft 24. The pin is provided with a reduced neck portion 31 and a head 32 which may be engaged by the end of the screw 27 when it is tightened in place. Upon so mounting thewrench and securing it in place by the screw 27, the head 25 of the work and the connecting key 26 will be rigidly secured together and'to the wrench, so that the same may beturned by grasping and manually turning the rod33 extending diametrically through the head 280.

In operation, the connecting key 26 is placed in position over the head 25 of the shaft 2 1. The wrench is then mounted in place so that the pin extends downwardly through said head 25 and is rigidly secured therein by the screw 27 The shaft 24 with in the central opening 3st of the vise and held therein by the screw The handle 19 is then turned so as to force the tool 17 forwardly until the flanges 21 of the rollers 20 engage the periphery of the connecting key 26. The holder or vise 11 and its associated parts are so constructed that the flange 21 will be immediately opposite the recess 225 formed about the periphery of the head 25 whereby upon further turning the handle 19, the roller flanges 21 will force the metal of the surrounding shell into said recess. Upon then grasping and turning the rod 33, so that the connecting key is turned with respect to said rollers, the connecting shell surrounding the groove 28 will be rolled therein and the bead connection will thereby be formed.

In accordance with the aforestated main object of my invention, the key 26 is an ex ample of the female type work which my invention is adapted to receive and 2a is the corresponding male member, it being desired to lock said male member in coupled engagement within said female member by means of the rolling operation above described. L. is understood that said male member is dis posed within said female member in free rotatable relation in respect thereto, said members forming with each other thereby what is known as a running fit. It is therefore import-ant in rendering said members in beaded engagement as above described, thatv the bead rolling operation should not be continued longenough to engage said tongue in tight contact with the recess 28. It is therefore important that the head 280 be manually rotated by means of the rod 33, as before described, so that the operator may readily ascertain when the afore-described rolling operation has been completed, it be ing understood thatwhen said tongue has been rolled suliiciently deep enough into said recess said tongue will begin to bind frictionally within same and thereby resist the manual rotation of the key 26 and-the head 280, by which the operator will know when the rolling operation is complete, as. this will automatically prevent the key 26 from being engaged rigidly to the head 25.

Referring again to the thumb screw 27 which engages the neck 31 of the pin 30, as before mentioned the threaded end of said screw terminates in a conical or nose type point. It will also be observed that the lower surface of the neck 31 is of conical or bevel shape. In accordance with this the screw 27 is suitably located in the head 25 so that said screw will engage the neck 31 on the conical surface of said neck, being suitably located to bring the bevel surface of Said screw end in contact with said conical surface of the neck 31 by which arrangement engagement of said screw with. the head 32 will cause said pin 30 to be cammed downward within the hollow pin 24, the key 26 being thus firmly clamped thereby, on the head 25, the tightness of which relation may be varied as desired by correspondingly varying the tightness of the screw 27 against the head 32. 4

Referring to the central opening 34, in the standard 11, more particularly as shown in Fig. 1, attention is called to the V shaped structure formed within said opening by the vertical surfaces 35 and 36 which are arranged symmetrically in regard to the screw 22 and the rollers 20. Still referring to Fig. 1, the dotted lines 37 indicate the normalposition of the hollow shaft 24 within said opening. it will be noticed that pressure of the screw 22 against said pin confines said pin between the surfaces 35 and 36 and the end of said screw, said pin being thus centralized by said surfaces in relation to the rollers 20 and thus held in suitable position for the rolling operation.

Referring again to the head 280, the upper portion of said head, it will be observed, forms-a sleeve structure in which is formed a radial notch 38 in the upper edgethereo'l, as shown in Fig. 2 by which arrangement said head forms a somewhat special spanner wrench more particularly adapted under certain conditions to engage the pin 24 when the head 280 is in reversed position in respect to said pin in which case said notch engages the screw 27 and the said sleeve formation of the head 2S0 engages the head 25, said head being in reversed relation in respect to Fig. 2 and Fig. 3. By this arrangement the head 280 will serve as a hold er or wrench for the pin 24 as desired when performing other work on said pin, not described herein.

Referring again to the screw 27 in respectto the neck 31 it is understood that said neck together with the pin 30 and the head 280, may be rotated independently in respect to the screw 27, in which case said screw will be in frictional engagement with said neck.

While I have illustrated in a general way, certain instrumentalities which may be employed in carrying my invention into effect, it is evident that many modifications may be made in the various details, without departing from the scope of the appending claims, it being understood that my invention is not restricted to the particular forms herein described.
